Hi I've been thinking of a project (nothing to do with college work) for me to do for a while now and finally came up with making a darts scorer as I can't find a diy one online. So I went to my crocodile technology and started mocking up a circuit. So far I have designed a 16 bit adder and when I tested it I happily saw it output binary in the correct way, however I then tried to simulate a 7 segment display unit connected to the adders outputs I couldnt get it working. So that is my question how do I wire up 7 segment displays? Extra Info: The adder has 17 outputs (including the carry output) It needs to connect to 4 seperate 7 segment display The displays should not go past 9 (i.e goes to 0 and increases next display) Thanks in advance.
